8 S910xA SCPI Programming Commands

8. 0. 8. 1 Example of Controlling the Secondary Transceiver Source

In this example, SCPI commands are used to turn on a system configuration with a
Secondary Transceiver Source ("Blocker" signal also referred to as an "interfering"
signal), after both signals have been loaded and are playing on individual M9410A
PXIe VXTs.
// Configure settings common to both sources
ScpiCommand(":SOUR:CONF:PORT " + SignalPort + ";");
ScpiCommand(":SOUR:CONF:POW:OFFS " + OtaLoss.ToString("G6"));
// Configure the Primary signal
ScpiCommand(":SOUR:CONF:PRIM:FREQ " +
PrimarySourceFrequency.ToString("F2") + ";");
ScpiCommand(":SOUR:CONF:PRIM:POW:AMPL " +
PrimarySourcePower.ToString("G6") + ";");
// Configure the interfering signal
ScpiCommand(":SOUR:CONF:SEC:FREQ " +
SecondarySourceFrequency.ToString("F2") + ";");
ScpiCommand(":SOUR:CONF:SEC:POW:AMPL " +
SecondarySourcePower.ToString("G6") + ";");
ScpiCommand(":SOUR:CONF:SEC:BAND
SecondarySourceBandwith.ToString("G6") + ";");
// Enable the dual source function, which is very sticky
// - need to disable for VXTIIs to work correctly.
// Need the *OPC? to make sure errors have time to
// make it into the queue before continuing
ScpiQuery(":SOUR:CONF:STAT 1;*OPC?");

Because
:SOUR:CONF:STAT 1;
system to support an interfering signal, it should be
followed with
:SOUR:CONF:STAT 0;
secondary source is complete.
The wanted signal can be on either the primary or
secondary M9410A PXIe VXT.
